 The trailing suction hopper dredger (TSHD) Scheldt River was officially named  at the DEME head office in Zwijndrecht, Belgium. The dredger was named by Veerle Hegge, the wife of Bart De Wever, Mayor of Antwerp.

The 8,400 m³ Scheldt River is the second dredger in the DEME fleet equipped with dual fuel engines. The highly innovative vessel can operate in LNG mode, reducing carbon dioxide emissions, almost eliminating sulphur, NOx and particle emissions. LNG is intrinsically clean and there is no need for exhaust gas cleaning systems
Scheldt River was built at Royal IHC’s shipyard in the Netherlands. The new vessel is part of DEME’s multi-year fleet investment programme, focused on further increasing efficiency, both in terms of productivity and environmental performance. 
Scheldt River boosts great dredging performance in shallow waters and meets and exceeds all current emission regulations, even in the  emission control areas such as the North Sea.
Scheldt River is equipped with two speed propulsion gear boxes and combinatory mode propeller thrust control, which will result in at least 10 percent fuel savings during dredging operations.. The vessel also has a Dynamic Position & Dynamic Tracking (DP/ DT) system, further enhancing manoeuvrability and position keeping. 
The dredge pump of ‘Scheldt River’ is driven by a hybrid drive-diesel direct plus electric motor. Efficient power management solutions are made possible, and the dredge pump is achieving an excellent performance both in trailing and in shore discharge mode. 
’Scheldt River also features a one man bridge operation, increasing efficiency and ease of handling. Scheldt River is designed and built to allow Extended Dry Docking Service (7,5 years), meaning less time lost in dry-dock.
Earlier this year the dual fuel trailing suction hopper Minerva entered the DEME fleet. The vessel is currently executing trenching works for the Rentel offshore wind farm near the Belgian coast. In the near future, both Scheldt River and Minerva will be deployed for the seabed preparation for Elia’s Modular Offshore Grid (or so called electricity plug) in the North Sea. In the next two years the dredging fleet will be further reinforced with the TSHD Bonny River (2018) and the cutter suction dredger Spartacus (2019).
On October 1, DEME will present Scheldt River to the general public during “Open Bedrijvendag”, a nationwide event where companies open their doors for visitors. During the open day job seekers can also get information on the many job opportunities at DEME. More than 200 new employees will be recruited to meet the demand driven by the growth in several activities, including the offshore wind and infra marine industry.
